Noticed my grid usage is oddly odd, battery system slow to respond. Then spotted this error
Any ideas anyone?
I’m not sure if the two are related. Need more detail re oddly odd.
As for the blue message above, a number of people are saying the web portal isn’t working properly - I suspect that is a database error (locking what? Locking process maybe?).
The portal misbehaving wouldn’t usually cause inverters to misbehave - the portal and inverter do talk to each other, e.g. passing commands and statistics, but who knows, I guess there’s always a chance.
Locking relates to a new-ish feature available in the API - GivEnergy API Documentation (v1.40.0)
It allows 3rd parties to stop owners changing settings. Cant really think of a reason this would be deployed in a domestic setting other than:
If your on intelligent flux - youve handed control over to Octopus - so it stops you reversing their changes
Or
Your in the middle of an Axle grid event and it stops you from dropping your inverter out the VPP which could destabalise the grid if enough people did it.
Im on Intelligent flux and i dont see this so unless you were in the middle of an Axle grid event (which at best would likely be no more than an hour) then ive no idea why its been deployed on your account.

Ok the oddly odd comment. I have an EMS with 3 AC3’s with a battery on each. What I was seeing was if I applied a load, charging the car say. Then my batteries would either supply 33% or 66% of the required load. It looked like 1 AC3 was not playing ball. Also checked the battery capacities and 2 were in perfect sync 80% each and the other was at 89% which does not happen with the EMS.
The power issue, the lights in my house went extremely bright before dimming. A few devices restarted but everything seemed ok. I do have dimmable lights in my home but I have no control to make down and up go bright at the sametime. But yes I expect this was unrelated to the inverter lock issue.
However, everything is now working normally again.
@TerraVolt I have been going through my logs this morning and can see API events from SERVER changing my AC discharge setting. I have signed up to the new AXLE grid events for none octopus customers but as yet i have not seen an event or been told one was coming. This grid load issue happened from around 7:30pm until midnight. Since then everything reverted to normal.
I’d be very suspicious of Axle then.
There has been issues in the past with settings not reverting properly. Pretty sure some moans on here or the other giv forum
As for the lights getting very bright, I’ve seen that happen when there was a fault in the road.
Can’t recall the exact reason, maybe dodgy supply cable or dodgy main fuse.
It might be a good idea to get an electrician to check your circuits (I think this is recommended every ten years - EiCR or something like that?). OR call the DNO and mention the lights getting very bright and dim and perhaps they can check supply side.
It may be something completely unrelated to the above of course, but might be best to be on the safe side.
AH you have EMS - so they are really picky about changes on the inverters directly - everything should always run through the EMS and then it dishes out commands (GivTCP directly into the inverters is another no no.)
Is it still saying locked? if so, I wonder if the locking is now being implemented on EMS installs - so the end user can’t mess with the individual inverters but can change things via the EMS route only.
I assume the EMS has it’s own account that you can use for control & the app links to that as well rather than each inverter?
It is all sorted now. It was an Axle event. I have asked to remove myself from the trial, I am in the process of moving house anyway so best not leave the new owners setup like this!
